The list author says: "Try these contemporary series for YA girls. I'm not opposed to sci-fi or paranormal or fantasy (I've read all the Twilight books and am working my way through Hunger Games), but you can read about every-day girls and find a powerful story. Also, you don't have to have poor little rich girls or private school drama to have a good series, although a couple of the series listed here have those as well. I have included a few books with sequels and authors who turn out consistently good stand-alone books. These books are all for older teen readers."
"Cabot has a middle-grade contemporary series about a princess in hiding as well as series about a kick-boxing ghost shrink, Arthur reincarnated, a lighting-struck person-finder, an unlucky teenage witch and a body-snatching supermodel, but only her stand-alone books fit this list."
